FIG. 21 is a diagram showing the current state of the conventional transmission line, its problems, and the purpose of the present invention. In the conventional integrated wiring system, as shown in FIG. 20, a video system has a bus-shaped topology, an audio system has a star-shaped topology, and a data system has a bus-shaped / star-shaped / ring-shaped topology. Since the topologies are different, integrated wiring that integrated all media was not possible. Therefore, the wiring could not be used effectively. When a new device is introduced, completely different wiring may be necessary or completely different topology may be required, and in many cases, even if the preceding wiring is performed, the work of re-laying the wiring eventually occurs. In addition, since there is no patch panel 4 that can be electrically controlled at present and the patch panel 4 is manually changed, the size of the patch terminal becomes huge and the construction work takes time, and human work is required. Furthermore, it is necessary to always manage the connection status with documents,
It is not possible to respond to a major configuration change. Also, changing the network topology itself is not possible with current wiring systems.

The present invention has been made to solve the problems of the conventional wiring system, and an object of the present invention is to provide a transmission line that can handle all kinds of media. Moreover, it aims at providing the apparatus used for providing the transmission path. In addition, it is possible to construct a network in stages so that it can cope with the advent of new communication equipment terminals, supply transmission paths of all network topologies required for equipment, and waste transmission media pre-wired. Intended to be used effectively.

1 to the active patch 22 and the video node 30. However, the setting method of the cross connector 21 is different from the ring shape and the star shape. A switch 32 is provided at one end of the cross connector 21 so that it can be folded back. This switch is OFF in the case of the ring-shaped / star-shaped topology, but is turned ON in the case of the bus-shaped so that the information can be returned and transmitted to the receiving terminal. With this configuration, broadcast communication, which is a feature of the bus-like topology, can be smoothly performed.
